Gears & Axles - Calling M6 cars with 4.10s and the stock 10 bolt
05-05-2012, 11:51 PM
All I keep reading about is how weak the stock rear is, and how putting 4.10s in the back never live. Has any one's car lasted with 4.10s and the 10 bolt? My car recently bent a axle and I really can't see spending 3000 on a rear end when I don't go to the track. All I like to do is scoot down the road sideways and do a highway pull once In a while. So if your rear has lasted a bit post up and let me know.
I plan on putting one stronger cover and upgrading to superior axles, if this will last for another 20k I would be more then happy.

I think as Long as you have some bs tires and dont hook up and or dump the cluth at 6k everytime youll be ok for a lil while but still ivesting in a newer rear will be better for you

It really depends on how you drive the car. Both my 10 bolts I ran in my past Z28 and current WS6 have held up just fine. On the flip side, I don't beat on the car nor drag race it. The only thing I do other than cruise in it is freeway/backroads roll racing. I'm putting down over 400+rwh & rwt and so far so good. Until it goes POP, I'm going to keep it as is and then a S60 will be going in.

My 10-bolt with 4.10's running Hoosiers is holding up just fine. I've had 5-6 1.6x 60's and 8-10 1.7x 60's my last two visits to the track after my cam install. This rear end also had 20-30 track passes on it when my car just had bolt-ons running street tires.
This was a 4-5k launch w/ a 1.63 60:
Bias Ply tires are the key as they take a lot of the shock from the drivetrain on the launch and shifts. Slipping the clutch of the hole is also necessary. 10-bolts being worked hard are definitely on borrowed time, but they can last. Wheel hop and clutch dumps will kill them pretty fast. Some guys will break them pulling 2.0 60 ft's because they dump the clutch from 2-3k and/or get wheel hop.

I have had 4.1-'s in my 10-bolt since 2004. I only made to passes on street tires with them (talk about crappy 60' times). They have been on drag radials on the street since soon after that. So far so good. Rarely launch the car too hard. Mostly cruising and enjoying the car.
My rear blew up shifting into 4th on street tires. But I have no suspension or anything done and get insane wheel hop.. well had. I recently rebuilt it and put a lpw girdle on and also adding a axle tube brace tomorrow. Def feels stronger already, but I got some good use out of mine the way it was and beat on my car hard, often.

I've never had one of my 10 bolts I rebuilt break, and I've done at least a dozen. I really believe fresh bearings do a lot for the overall strength of the unit and keeping everything in alignment.
